Tapping: you bouncing your pencil point or your finger on a desk. Taping: you using tape to wrap a present.
it will go in a circle or a line that is are science fair
When you listen to a pencil tapping, the sound you hear is vibrations being transmitted through the air. As the pencil taps, it creates a disturbance in the air molecules, which in turn creates sound waves that travel through the air to your ears, allowing you to hear the tapping noise.
When you place your ear on the desk and listen to the sound of pencil tapping, that sound becomes amplified because the desk acts as a resonating chamber. When you lift your ear off the desk and listen to the tapping in the air, the sound may seem quieter or different because there is less direct contact with the surface to amplify the vibrations.
You first pick a tempo and start beating your wrist against a table. Then you get a pencil and pick another tempo and start tapping it at the point of the pencil. Then you can slam the whole pencil on the table lets say every four taps of the point of the pencil. Then you could get creative.

No, earthworms cannot hear, but the feel the vibrations through the ground. That is their form of sight and hearing.
A pencil can vibrate when a force is applied to it, causing it to oscillate back and forth. This vibration can be initiated by tapping or shaking the pencil, leading to the movement of its particles in a wave-like motion.
To fix a jam in your Bic Velocity pencil, first try gently tapping the pencil against a hard surface to dislodge the lead. If that doesn't work, carefully use a small tool like a paperclip to remove the jammed lead from the tip of the pencil. Be sure to do this with caution to avoid damaging the pencil.
Touching an earthworm with a toothpick would likely not harm the earthworm as toothpicks are not sharp enough to cause physical injury to the earthworm's body. However, the earthworm may perceive the touch as a form of stimulation or disturbance and may react by retracting back into the soil for protection.
